1. Overview

dplyr package is the most powerful package for data handling in R, and it has also the ability of working with databases(See Vignette).
But the functionalities of dealing with databases in dplyr is begin developped even now.
Now, I'm trying to make dplyr with databases more comfortable by some functions.
For that purpose, I've created dplyrr package.
dplyrr has below functions:

load_tbls() : Easy to load table objects for all tables in a database.

cut() in mutate() : Easy to create a case statement by using the grammar like the base::cut().

count_if() and n_if() in summarise() : Shortcut to count rows that a condition is satisfied.
